A White House source has told RTÉ News that "negotiations are ongoing" regarding a possible visit to Ireland by US President Donald Trump.
The person added that until those negotiations have been completed, no announcement will be made.
There has been much speculation that Mr Trump is due to visit Ireland in early June but the White House has said that it will not be making any announcement at this time.
The Irish Government said it has yet to receive any official confirmation of a visit.
A secret service advance team visited Donald Trump's golf resort in Doonbeg, Co Clare, in recent weeks to assess security ahead of a possible visit.
Mr Trump will be in Europe next month for a state visit to the UK between 3-5 June and a D-Day commemoration in France on 6 June.
During his St Patrick’s Day meeting with the Taoiseach at the White House in March, the US president said he planned to visit Ireland this year.
Leo Varadkar later said that the visit may happen in June when Mr Trump travels to Europe.
